Abstract

We study quantum properties of SU(21)(2|1) supersymmetric (deformed N=4{\cal N}=4, d=1d=1 supersymmetric) extension of the superintegrable Smorodinsky--Winternitz system on a complex Euclidian space CN\mathbb{C}^N. The full set of wave functions is constructed and the energy spectrum is calculated. It is shown that SU(21)(2|1) supersymmetry implies the bosonic and fermionic states to belong to separate energy levels, thus exhibiting the "even-odd" splitting of the spectra. The superextended hidden symmetry operators are also defined and their action on SU(21)(2|1) multiplets of the wave functions is given. An equivalent description of the same system in terms of superconformal SU(21,1)(2|1,1) quantum mechanics is considered and a new representation of the hidden symmetry generators in terms of the SU(21,1)(2|1,1) ones is found.
